METHOD OF MAKING TY PE.

- Application filed April 16,1917.

To all whom it may concern:

Be it'known that 1, JOHN J. VAN Ho- TEGEN, a citizen of the United States of America, and resident of St. Louis, 'Mis-- souri, have invented certain new and useful Improvements in Methods of Making Type, of which the followingis a specification, T containing a full, clear, and exact description, reference being had to the accompanyweld lugs on to individual letter types, andtoiplates"containing type of various size ing drawings, forming a part hereof.

The object of my lnvention is to devise a method of making type; especially to and arrangement, and moreespecially on electro" type to he used on the segmental drums of multigraph machines.

At the present time the method'in vogue in securing the type to'the'segmental drums of multigraph machines is by means of metal circumferential bands which hold the various lines of type in position. \Vhen such bands are used, the type are not held secure and are permitted to move relative to each other, causing inferior printing due to the fact that the face of the type is not in uniform contact with the paper, causing blotting and blurring on some portions and an insufficient impression on other parts of the face. Thisalso causes some portions of the type to wear appreciably. Since the type is secured to a cylindrical surface in longitudinal lines, and the contact of the various lines of type with the paper is made by the revolution of the cylinder about its longitudinal axis, it follows that the type faces cannot be plane surfaces, it their entire face is to come in contact with the paper on which the impression is to be made; but must have a finite radius of curvature slightly greater than the radius of the segmental drum. The larger the type, the greater is the necessity of the curvature of the type face.

By the conventional method of fastening type to the drum either by lugs or hands, since the lugs could only be fastened to type with plane surfaces, only small type could be taken.

\Yhen large type were fastened to lugs and their faces curved on a finite radius, the lug was loosened from the type. The largest individual type that can now be fastened to the lugs is what is known as 18 point, 2'. 2., type i" in height.

Specification of Letters Patent.

Serial No. 162,494..

' Thepresent method" ofweldingtype to lugs consists in spot welding'with a blow torch; the'solder is'applied in spots along the surfaces of the back of the type and the lugs that are to be united and then the heat applied. This does not secure a solid "joint since the space between the joints does not unite. The result is that the type gradually work loose from the lugs and become inoperative.

with the use of my improved solder, (for which Iain this day filing'an application My method together for U; Letters Patent) obviates all these difficulties and secures firm, rigid, solid and secure union 'betweenthe'type and lug.

With "the above ahd'other objectsi'in view,

tinyin-t enti'on"has relation to certain novel '-fea tu-res 10f" construction and operation which are described'in the following specification and illustrated in the accompanying drawings in which:

Figure 1 is a front elevation of a font of type.

Fig. 2 is a back elevation of the same font of type.

Fig. 3 is a cross section on the line 33 of Fig. 1.

Fig. 4 is a front elevation of a line of type out from the font illustrated in Figs. 1 to 3 inclusive.

Fig. 5 is a back elevation of the line of type shown in Fig. 4.

Fig. 6 is a cross section on the line 6-45 of Fig. 5.

Fig. 7 is a front elevation of the letter cut from a line of type shown in Figs. 4 to 6 inclusive.

Fig. 8 is a back elevation of the letter shown in Fig. 7.

Fig. 9 is a cross section on the line 99 of Fig. 7.

Fig. 10 is an end elevation of the segmental drum of a multigraph machine.

Fig. 11 is a plan vieW of the drum shown in Fig. 10.

Fig. 12 is an enlarged fragmental sectional elevation of a portion of the back of type (a) and of the lug (/1).

Fig. 13 is an enlarged fragmental sectional elevation of the back of type and the T lug welded together.

l-l designates a row of letters on the font shown in Fig. l, and 15 the T lug secured to the back of row ll.

16 designates one of the letters in the row 14, and 17 the T lug secured to its back and 18 designates the T slotin the segmental.

drum shown in Figs. 10 and 11.

WVith the material described above my method of securing lugs to individual type of any size, with faces of the required curvature for use in multigraph machines is as follows:

A font of type, with the desired letters thereon, as shown in Fig. 3, without the T lug on its back, the distance bet-ween the letters being uniform and of the thickness of a hack saw, is secured as are T lugs such as shown at b, Fig. 12; as many T lugs will be required-as there are lines of type on the font. My specially prepared solder,

(composed of tin, lead, glycerin and alcohol, for which I am this day filing application for Letters Patent) is then applied to the back of each row of type and to the end of the T lug that is to be secured to the font, (as-shown in Fig. 12). The lug is held in contact with the font as shown by Figs. 2 and 3, and the flame of a blow torch applied to the solder atthe juncture of the lug and font; the solder will then melt and the juncture between the lug and font is complete. This process is repeated with the lugs on the back of each row. The font is now bent to the proper radius of curvature bythc conventional means (a well known machine is made for that purpose). The rows of type are then cut apart, by conventional means along the dash lines indicated on Fig. 1, and form the rows 14. The type, of rows such as 14, are then cut apart as indicated by the dash lines on Fig. 1. Since the type were properly spaced on the font, they are now in condition to be placed on the drum shown in Figs. 10 and 11, the T lug 17 sliding into the slots 18.

I claim:

The process of making individual type which consists in soldering or securing lugs in rows to the backs of fonts of type, each lug being secured to a row of type, then bending the font toa selective radius of curvature, cutting the rows apart, and then cutting the individual letters of each row apart. 7

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
